UGC NET Questions (Paper – 1)

Content validity concerns whether the items in a test or questionnaire are representative of the entire domain of content they are supposed to measure, such as a course syllabus or topic area. Subject experts often review the instrument to judge whether important areas are adequately sampled. High content validity reduces the chance that important facets of the construct are omitted. Therefore, the coverage-focused validity described in the stem is correctly called content validity.

Option A:
Option A, content validity, is especially important in achievement tests where missing topics can bias scores. When an instrument aligns well with specified learning outcomes or a blueprint, it demonstrates strong content validity, matching the stem exactly.

Option B:
Construct validity addresses whether the instrument truly measures the underlying theoretical construct, based on patterns of relationships with other variables and factor structure. It goes beyond simple content coverage, so it is not the best fit for this question.

Option C:
Criterion-related validity evaluates how well test scores correlate with an external criterion, such as job performance or future grades. It deals with predictive or concurrent accuracy rather than domain coverage. Hence, it is not appropriate here.

Option D:
Face validity refers to the extent to which a test appears to measure what it claims to, based on superficial inspection by users. It does not involve systematic analysis of content coverage, so it is not the correct answer.

Split-half reliability is obtained by dividing a test into two comparable halves, such as odd and even items, and correlating the scores on these halves. A high correlation indicates that the items within the test are consistently measuring the same construct. This method assesses internal consistency without requiring separate test administrations. Because the stem describes estimating reliability by correlating scores on two halves of the same test, it is clearly referring to split-half reliability.

Option A:
Test–retest reliability involves administering the same test to the same group of individuals on two different occasions and correlating the scores across time. It measures stability over time, not the internal consistency between halves within a single administration. Therefore, test–retest does not match the description in the stem.

Option B:
Parallel forms reliability is established by developing two equivalent versions of a test and correlating the scores obtained on them. It assesses consistency across forms rather than across halves of one form. Since the question mentions halves of the same test, parallel forms is not the correct answer.

Option C:
Split-half reliability directly evaluates how well different items in a single instrument work together to measure a construct by comparing performance on different subsets. This internal consistency focus corresponds exactly to the procedure outlined in the stem, confirming split-half as the appropriate completion.

Option D:
Inter-rater reliability refers to the degree of agreement between different observers or raters when scoring or judging the same behaviour or responses. It deals with consistency across raters rather than across test halves, so inter-rater is not suitable here.

Content validity focuses on whether the items of a test collectively cover the objectives and content specified in the curriculum or syllabus. Experts examine the extent to which the test samples important topics and cognitive levels in appropriate proportions. High content validity means that inferences about mastery of the subject based on test scores are well supported by the match between items and domain.

Option A:
Option A refers to reliability—specifically, the stability or consistency of scores over occasions—which is a different psychometric property.

Option B:
Option B correctly captures the essence of content validity as domain representation, emphasising expert judgement about how well items cover the specified content.

Option C:
Option C concerns criterion-related validity, which is about correlation with an external standard such as future performance or another established test.

Option D:
Option D focuses on physical attractiveness and printing quality, which may affect motivation but do not determine validity.

Statements A, B, D and F are accepted views about behavioural objectives. A is true because they express outcomes in observable terms. B is true since conditions and performance standards clarify expectations. D is true as behavioural objectives provide a basis for teaching and assessment, and F is true in pointing out that overemphasis can narrow focus to what is easily measured. C is wrong because vague verbs do not make objectives behavioural, and E is wrong because behavioural statements are widely used in cognitive objectives as well. Therefore, C and E only are the wrong statements.

Option A:
Option A isolates C as the only wrong statement but ignores E, even though limiting behavioural objectives to the psychomotor domain is also incorrect. Because it omits one of the wrong statements, C only is not sufficient.

Option B:
Option B correctly identifies C and E as the problematic statements. It recognises that vague verbs and domain restriction both contradict the idea of clear, observable outcomes across domains, while leaving A, B, D and F as accurate. Hence C and E only is the correct option.

Option C:
Option C treats only E as wrong and overlooks C, despite the fact that verbs like “know” and “understand” are criticised for being non-behavioural. This partial identification makes E only an incomplete answer.

Option D:
Option D adds F to the set of wrong statements, but F actually expresses a valid caution about overemphasis on measurement. Including a true cautionary statement among wrong ones means C, E and F only is not acceptable.

Content validity concerns whether the items of a test or instrument appropriately sample the entire domain of content that the test is supposed to measure. For example, an achievement test in research aptitude should include items across major topics such as types of research, sampling, tools and ethics, in proportion to their importance. High content validity arises when subject experts judge that the blueprint and items adequately cover the specified domain. Since the stem speaks of representing the full domain of content, it is clearly referring to content validity.

Option A:
Construct validity deals with whether a test truly measures the underlying psychological construct or trait it claims to assess, such as intelligence or motivation. It involves evidence from multiple sources, including correlations with other measures and experimental studies. Although related, construct validity focuses on the abstract construct rather than coverage of the content domain, so it is not the correct answer here.

Option B:
Criterion-related validity examines how well test scores correlate with an external criterion, such as future performance or another established measure. It is concerned with predictive or concurrent relationships, not with the breadth of content represented by the test items. Therefore, criterion-related validity does not match the emphasis on domain coverage in the stem.

Option C:
Content validity is often established through expert judgment, where specialists review the test blueprint and items to ensure all important facets of the domain are represented and that no irrelevant content is included. This process directly addresses the question of whether the test covers the intended content adequately. Because the stem focuses on this aspect, content validity correctly completes the statement.

Option D:
Face validity refers to the superficial impression that a test appears to measure what it is supposed to, based on the views of laypeople or examinees. It does not require systematic analysis of domain coverage and can be misleading. Since the stem asks about adequate representation of the full domain, face validity is not the appropriate term.
